1results about How to "Improve flight characteristics" patented technology

This invention relates to a rotor hub and rotor with a flexible hub axial hinge, belonging to the field of helicopter technology, and solves the problem of poor aeroelastic stability of helicopter rotors caused by the inefficient absorption of rotor shimmy. The rotor hub with a flexible hub axial hinge of this invention includes a central component assembly and a flexible hub axial hinge; the flexible hub axial hinge includes a functional part and a limiting part, with the limiting part disposed between the central component assembly and the functional part; the limiting part includes a support shaft assembly and a lower limit motion assembly; the functional part includes a sleeve, a tension / torsion plate assembly, and a stacked shimmy damping assembly. The rotor hub of this invention has composite damping, which can efficiently absorb the centrifugal force and shimmy of the blades, ensuring both maneuverability and responsiveness while maintaining stable flight; the rotor of this invention can improve the flight performance of helicopters.
